Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings.
The micro speaker housing shown in fig. 1 comprises a first housing 1 and a base 2, wherein a mounting portion 21 for mounting a speaker unit is arranged on the base 2, an opening portion 11 and a guide portion 12 are arranged on a side wall of the first housing 1, positioning clamping grooves 13 are respectively arranged on a top wall and a bottom wall of the first housing 1, and the positioning clamping grooves 13 are close to the opening portion 11; the base 2 is provided with a clamping block 22 matched with the positioning clamping groove 13, the base 2 is clamped with the first shell 1, and when the base 2 is assembled with the first shell 1, the base 1 moves along the guide part 12 of the first shell 1 and the base 2 blocks the opening part 11. The guide portion 12 has guiding and coarse positioning functions, so that the fixture block 22 on the base 2 can easily enter the positioning fixture slot 13 on the first housing 1, and the base 2 can be easily pushed into the first housing 1 along the guide portion 12 and combined with the first housing 1 during assembly.
Two sides of the opening part 11 of the first shell 1 are respectively provided with a dislocation-preventing limit baffle 14. When the micro-speaker shell is installed in an electronic product, the micro-speaker shell is glued or installed with the electronic product in other connection modes, and the limiting baffle 14 can prevent the first shell 1 and the base 2 from being dislocated.
The preferred structure of the speaker of this embodiment is such that the first casing 1 is a square casing, and openings 11 are provided in three adjacent side walls of the square casing. The base 2 comprises a push plate 23 and side plates 24, the side plates 24 are respectively arranged on two sides of the push plate 23, mounting portions 21 for mounting the loudspeaker bodies are arranged on the inner side walls of the two side plates 24, and clamping blocks 22 are arranged in the middle of the inner side walls of the push plate 23.
